1947 Indian motorcycle startup and ride off (Alec MacKaye)
Alec MacKaye starting up and riding his 1947 Indian on the mean streets of
Washington, DC. Throttle is on the left handle bar, right handle bar is
timing advance (twist it and the distributer moves back and forth witch
advances the timing), clutch is left foot pedal, rear brake is right foot
pedal, and the front brake is the right handle bar level like current
motorcycles. This guy bought this bike 25 years ago, before they were
cool.

I`ve got many nice comments for making the "Honda Cr 125 piston / top end
rebuild" movie. In this movie, I show in good detail how to chance the
piston on your two stroke Honda Cr 125.
A similar movie for the Honda Cr250 would be nice, and that's what I have
made.
Hope you like it!
The bike used in this movie is a 2007 Honda Cr250.
Always use the right manual for your bike! The 2002-2007 Honda Cr250 bikes
are very much alike but there are some changes. That's why the right manual
for your year is important.
Good luck!

Turbospoke - The Bicycle Exhaust System
Buy here: http://www.speedwaymotors.com/turbospoke,50683.html
turbospoke is a complete Exhaust system that fits to any bike and makes
it look and sound just like a real dirt bike. turbospoke is based on the old
'baseball-card-in-the-spokes' concept, brought right up to date. The
realistic engine sounds are created using long lasting plastic cards, a
clever sound chamber and an awesome megaphone Exhaust pipe which really amplifies the sound.

Apparently if you hit the front brakes too hard the back end will come up

Pocket bike start
www.bigmotorsport.com
A general idea of how to start your pocket bike.
1) Make sure the choke is in the closed position.
2) Drop the bike a few times on the back tires to get rid of any air
bubbles that may have formed.
3) Prime the engine using slow pulls.
4) Pull the cord at the same angle it is coming out of the pull start
assembly. Otherwise you will not be able to pull fast enough to start
engine, and may cause damage to the pull assembly. If you are lifting the
bike in the air, you are not pulling it at the right angle.

Profile:
I started racing in 1964. Computers were still not there. I did hardly no
calculation. With the advent of the computer everything has changed and
complicated calculations are no problem any more. All old historical notes
were struggling. In the past 15 years I got a number of programs. Beside I
did developed many programs myself in Excel. It was my profession to do so
for my employer for many years.
In 2003 also began making calculations for third parties. Not everything,
but a lot can be calculated very accurately for any twostroke engine. For
instance the Exhaustpipe can be
calculated in almost exactly the correct speed for which the setup and
cylinder is optimal. Even by a large kart engines manufacturer (TM) was
found to be not entirely correct. With a new calculated combustion chamber
and Exhaustpipe it was far better then
before.
This is also partly due to the information I got from Jan Thiel and was
freely available after retiring from Aprilia racing end 2007.
Also the UltraSap ignition developed by my son Raimond was a very important
part. The combustion and power are strongly influenced. Read about this
